how to increase andy in javascript

To increase the value of a variable in JavaScript, you can use the addition assignment operator +=. Here's an example:

index.tsx
let andy = 10;
andy += 5; // now andy is 15
44 chars
3 lines

In this example, we start with a variable andy with a value of 10. Then we use the += operator to add 5 to andy, resulting in a new value of 15.

Alternatively, you can also use the increment operator ++ to add 1 to a variable. Here's an example:

index.tsx
let andy = 10;
andy++; // now andy is 11
41 chars
3 lines

In this example, we start with a variable andy with a value of 10. Then we use the ++ operator to add 1 to andy, resulting in a new value of 11.
